dc.description.abstract | Forward osmotic pressure-free reverse osmosis (Δπ=0 RO) was invented in 2013. The first patent (US 9,950,297 B2) was registered on April 18, 2018. The “Osmotic Pressure of Concentrated Solutions” in JACS (1908) by G.N. Lewis of MIT was used for the estimation. The Chang’s RO system differs from conventional RO (C-RO) in that two-chamber system of osmotic pressure equalizer and a low-pressure RO system while C-RO is based on a single chamber. Chang claimed that all aqueous solutions, including salt water, regardless of its osmotic pressure can be separated into water and salt. The second patent (US 10.953.367B2, March 23, 2021) showed that a low-pressure reverse osmosis is possible for 3.0% input at Δπ of 10 to 12 bar. Singularity ZERO reverse osmosis from his third patent (Korea patent 10-22322755, US-PCT/KR202003595) for a 3.0% NaCl input, 50% more water recovery, use of 1/3 RO membrane area, and 1/5th of theoretical energy. These numbers come from Chang’s laboratory experiments and theoretical analysis. Relative residence time (RRT) of feed and OE chambers makes Δπ to zero or negative by recycling enriched feed flow. The construction cost by S-ZERO was estimated to be around 50~60% of the current RO system. | - |
